{"product_id":"773-091","title":"773-091","description":"Ensure your high-efficiency heating system operates safely with this high-quality two-stage air pressure switch. Specifically engineered for multi-stage gas furnaces, this air-proving switch monitors the vacuum pressure generated by the inducer motor to confirm that exhaust gases are being vented correctly. It features precise dual setpoints of -0.35\" WC and -0.40\" WC to maintain the delicate balance required for multi-stage combustion cycles. If your furnace is failing to ignite, cycling off prematurely, or displaying pressure-related fault codes, this replacement sensor is essential for restoring reliable performance. Built for durability and accuracy, it serves as a critical safety mechanism to prevent hazardous operation by ensuring proper airflow before the ignition process begins.\u003cbr\u003e\nType: Air Pressure Switch\u003cbr\u003e\nSize: Standard HVAC replacement component\u003cbr\u003e\nApplication: Used in residential two-stage gas furnaces and high-efficiency heating systems to monitor inducer motor performance and venting safety.\u003cbr\u003e\nSpecifications: Two-stage operation; Pressure Setpoints: -0.35\" WC and -0.40\" WC; Function: Air proving\/Safety shut-off; Compatible with vacuum-sensing HVAC applications.","brand":"BCFurnace","offers":[{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.40\" WC \/ 773-091","offer_id":47251253297437,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.40\" WC \/ 0130F00726","offer_id":47251253330205,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.40\" WC \/ 0130F00726S","offer_id":47251253362973,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true},{"title":"GOODMAN PRESSURE SWITCH 2-STG -0.35\" WC \/ -0.40\" WC \/ 141062","offer_id":47251253395741,"sku":null,"price":108.14,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/d4268d721c8a4d5295705ee38e945334.webp?v=1773957994","url":"https:\/\/bcfurnace.myshopify.com\/products\/773-091","provider":"BCFurnace","version":"1.0","type":"link"}
